BR21 Upper Ill Valley

Sundgau has loads of exceptionally-diverse hiking possibilities. Let yourself be guided along the Ill Valley where a string of half-timbered houses with flowered balconies will lead you along this varied region of ponds, forests, chapels and windmills. You’ll pass by Waldighoffen, the homeland of the poet Nathan Katz, then by Oltingue and its Paysan Museum, before arriving at Ferrette, a city of counts tucked away at the feet of the Alsace Jura!
